The average Flagstaff residential customer uses 65-100 gallons of water per day. If your water consumption exceeds this amount per household member, you may have a leak. The most common cause of leaks is toilets with sticking float valves. Dye tablets kits are available at the Customer Service counter in City Hall. Another cause could be if you have an underground "stop and waste valve" that is not in the fully closed position or is leaking.
